Camloc cowl fasteners

[fklarmeyer]

My maintenance guy texted me that the cowl fastener I’m missing, per picture I sent, is actually an aftermarket Camloc Stud and gave me possible part numbers. He says it depends on the size they used.
Crazy orders online some of them won 5 bucks but $31.00 in shipping.

Suggestions?

I believe the ebay may have the best deals but I don’t really know the size.
part numbers I believe pretain to these fasteners, but size may be way off.
Camloc stud part # 40S5-10S
Grommet part # 4002-OS
Retaining Ring part # 40F26-1
